Single Accumulator Charging Valves These MICO® Single Accumulator Charging Valves are designed for installation in an open-center hydraulic system between the pump and its relief valve and the downstream secondary hydraulic devices; for example, a power steering control valve and cylinder installed in the same hydraulic circuit. These single accumulator charging valves supply oil to an accumulator from an open center circuit on demand. This is accomplished at a preset rate, L/min (GPM), at a selected pressure and is constant within the preset pressure limits. The flow to the downstream secondary...

Dual Accumulator Charging Valves PRINCIPLES OF OPERATION These MICO® Dual Accumulator Charging Valves perform essentially the same functions as the single charging valves. When the dual accumulator charging valves are used in a split hydraulic brake system each individual axle is separately controlled. These dual charging valves charge both accumulators. The primary advantage of dual charging valves are that if half of the brake system fails the remaining half will continue to function. zz Uses power developed in the main hydraulic system These dual charging valves charge the accumulators from...
